Problems solved by technology

[0003] The existing tape structure, because the antistatic coating is located on a certain layer of the tape, and the existing tape is a multi-layer structure, and the antistatic coating can only protect the adjacent layer, which is different from it. The antistatic protection performance of the adjacent layer is very weak. Therefore, in the long-term use process, it will still cause static electricity accumulation, high-voltage discharge, damage to electronic components, and even cause fires in flammable parts such as batteries in electronic products, resulting in Security risks

Embodiment

[0048] Preparation

[0049] 1. Add bistrifluoromethanesulfonimidated trimethylpropyl quaternary ammonium salt (N 1113 NTf 2 ), and mix uniformly, coat the polyurethane with the substrate to form a coating, peel off the coating to form the base layer 1, and the width of the base layer 1 is 10mm;

[0050] 2. Coating the first pressure-sensitive adhesive layer 2 and the second pressure-sensitive adhesive layer 3 on both sides of the base layer 1 to form a stretchable removable tape;

[0051] When an antistatic additive is added to the first pressure-sensitive adhesive layer 2, the pressure-sensitive adhesive and bistrifluoromethylsulfonimidated trimethylpropyl quaternary ammonium salt (N 1113 NTf 2 ) is mixed and then coated; when antistatic additives are added in the second pressure-sensitive adhesive layer 3, the pressure-sensitive adhesive and bistrifluoromethylsulfonimidated trimethylpropyl quaternary ammonium Salt (N 1113 NTf 2 ) mixed before coating.

Abstract

The invention relates to the technical field of adhesive tape production, and especially relates to an adhesive tape easy to stretch and remove, and a manufacturing method thereof. The adhesive tape easy to stretch and remove comprises a base layer, a first pressure-sensitive adhesive layer and a second pressure-sensitive adhesive layer, the first pressure-sensitive adhesive layer, the base layer and the second pressure-sensitive adhesive layer are sequentially laminated, and the base layer contains a base material and an antistatic additive. The adhesive tape easy to stretch and remove comprises three layers, the middle layer base layer contains the antistatic additive, and the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer are respectively adjacent to the base layer, so the adhesive tape easy to stretch and remove has an antistatic effect, does not cause electrostatic accumulation even after being used for a long term, can avoid destroy and even fire accidents caused by electrostatic discharge, and improves the security of products.

Description

technical field [0001] The present application relates to the technical field of adhesive tape production, in particular to an easy-stretch removable adhesive tape and a manufacturing method thereof. Background technique [0002] The easy-stretch removal tape is widely used in the field of electronic products, such as the bonding and fixing of screens, batteries, and other components. Easy-stretch removal tape is usually made of polymer materials such as polyurethane, silicone polymer, rubber, etc., and the volume resistivity is usually in the range of 10 10 ~10 20 ohm·cm, it is easy to cause static electricity accumulation during long-term use. Existing solutions usually add an antistatic coating to the multilayer structure of the easy-stretch removal tape, that is, the easy-stretch removal tape includes at least four layers: base layer, antistatic layer, first pressure-sensitive adhesive Mixture layer and the second pressure-sensitive adhesive layer, the existing antist...
